【題目】Many young people want to become pop stars. It is their great ambition(雄心)in life. They think ： pop stars make a lot of money ； they lead interesting and exciting lives ； thousands of fans adore them ； they become famous.

Yes, but first they must become stars. Most performers start life with a group. This is the pattern nowadays. But there are many groups and the competition is hard. Groups appear and disappear almost overnight. Only a small number stay. Almost without exception (例外)they have to work very hard before they reach the top.

And very few reach the top and stay there. In England there are perhaps thirty or so groups at the top. Most of these do not earn so much money ； perhaps $ 400 each time they perform. What is more，they have quite a lot of expenses. They have to pay a manager, for example. He is the key person in their lives and he takes about 20% of their earnings—perhaps more. Then there are their clothes，their instruments and their van(車)

And don't forget they have to travel a great deal, sometimes 2,000 miles in one week. At times they even sleep in their van instead of a hotel, just to save money.

So now, what do you think? Are pop stars so rich? And do they have such exciting lives?

【1】Which of the following is the reason why many young people want to become pop stars?

A. Living an exciting life.

B. Being loved by thousands of fans.

C. Becoming rich.

D. All of the above.

【2】The right statement in the following about pop stars is that __________.

A. most of them fail to reach the top

B. they lead relaxed lives.

C. they can travel all over the world

D. they spend a lot of money on their clothes

【3】Why is the group's manager well paid?

A. Because he runs this group.

B. Because he looks after them.

C. Because he is important to them.

D. Because he buys them clothes and instruments.

【4】How do pop groups spend the money they earn?

A. They pay the manager 20% of their earnings or more.

B. They have to pay for clothes, instruments and their van.

C. They often make trips.

D. All of the above.

【5】The writer makes us believe __________.

A. it is pleasant to become a pop star

B. that if you work very hard in pop groups, you will reach the top

C. pop stars are neither too rich nor too happy

D. general persons had better not dream of pop stars

【題目】(Reuters) — A group of Chinese scientists and explorers are looking for international help to organize a new search for the country’s answer to Bigfoot, known locally as the “Yeren”, or “wild man”.

Over the years, more than 400 people have said they saw the half-man, half-ape (半猿) Yeren in a remote, mountainous area of the central province of Hubei, state news agency Xinhua said on Saturday.

Expeditions (探險) in the 1970s and 1980s found hair, a footprint, and a sleeping nest suspected of belonging to the Yeren, but there has been no conclusive proof, the report added.

Witnesses describe a creature that walks upright and is more than 2 meters tall with grey, red or black hair all over its body, Xinhua said.

Now the Hubei Wild Man Research Association is looking for volunteers from around the world to join them on another expedition to look for the Yeren.

“We want the team members to be devoted, as there will be a lot of hard work in the process,” Luo Baosheng, vice president of the group, told Xinhua.

But the team will have to come up with about 10 million yuan ($1.50 million) first, and is talking to companies and other bodies to secure the money, so there is no timetable yet for when they may start, the report added.

China is no stranger to cryptozoology. There are many tales about mysterious, monster-like creatures in remote parts of the country. For example, Tibetans have long talked about the existence of the Yeti (喜馬拉雅雪人), or “Abominable Snowman”, in the high mountains of their snowy homeland.

【1】What the volunteers for this expedition need most is _____.

A. experience B. enthusiasm

C. confidence D. devotion

【2】The timetable for starting the trip depends on _____.

A. the number of explorers

B. government’s support

C. the finance

D. local people’s guiding

【3】According to the text, the underlined word “cryptozoology” in the last paragraph probably refers to _____.

A. the study of mysterious animals

B. the study of human beings

C. dangerous expeditions

D. tourism industry

【4】What would be the best title for this text?

A. Volunteers for an expedition needed

B. Scientists to look for China’s Bigfoot

C. International cooperation in finding wild man

D. Yeren appeared in Hubei again

【題目】Earlier this month, California police cleared what was said to be the largest homeless encampment in the United States. About 200 homeless people were living at the camp in San Jose, California. Officials said police officers and city workers acted because the area was unclean.

The homeless people were living near Silicon Valley, the country's high technology center. Some people there have made millions, even billions of dollars from high-tech devices and services. But others have no money and no place to live.

Federal officials believe there are hundreds of thousands of homeless people nationwide on any given day. Each one lacks a permanent place to live. Reasons for homelessness can include the high cost of housing, poverty and unemployment. Other reasons are mental health problems and just plain bad luck.

In Los Angeles, a group called PATH searches along flood channels and major roads for homeless camps.. Its workers look for people who have no permanent shelter.

Jorge Guzman was one of the people hoping to help the homeless. He says they make their camps where they are not seen -- behind buildings or in forests or parks.

"They just don't want to be noticed. They're doing their thing out here and, you know, they're just trying to survive."

City workers periodically clear away small trees and plants, uncovering homeless campers. Workers in Whittier try to move people out of homeless camps and into a home of their own. But housing is costly. Still, worker Tomasz says he has been able to help some people.

"It's really good to see the steps when people are leaving their encampments and they're transitioning to either transitional housing, and after when they obtain their own housing."

But there are many other homeless people still living on the streets or in camps, moving when their campsites are taken down.

【1】Why did California police clear the homeless encampment?

A. Because the area was unclean.

B. Because the homeless people often fight.

C. Because the government has built new houses for them.

D. Because they badly affected the image of the city.

【2】Which is NOT the reason causing homelessness?

A. Mental health problems B. Plain bad luck

C. Being abandoned. D. The high cost of housing,

【3】According to the passage ,where may the homeless live?

A. In buildings behind parks.

B. In camps in forests.

C. In apartments near Silicon Valley

D. In permanent shelters.

【4】We can describe Tomasz as ____.

A. generous B. honest

C. grateful D. helpful

【5】Which of the following can replace the underlined phrase “take down”?

A. Write down. B. Break down.

C. Pull down. D. Set down.

【題目】B

A new study, led by scientists at the American Museum of Natural History, shows that living sharks are actually quite advanced in evolutionary terms, despite having retained their basic "sharkiness" over millions of years. The research is published today in the journal Nature.

"Sharks are traditionally thought to be one of the most primitive surviving jawed vertebrates（脊椎動物）. And most textbooks in schools today say that the internal jaw structures of modern sharks should look very similar to those in primitive shark-like fishes," said Alan Pradel, a postdoctoral researcher at the Museum and the lead author of the study. "But we've found that is not the case. "

The new study is based on an extremely well-preserved shark fossil collected by Ohio University professors Royal Mapes and Gene Mapes in Arkansas, where an ocean basin once was home to a diverse marine ecosystem. The fossilized skull of the new species, named Ozarcus mapesae. The heads of all fishes -- sharks included -- are segmented into the jaws and a series of arches that support the jaw and the gills（鰓）. These arches are thought to have given rise to jaws early in the tree of life.

Because shark skeletons are made of cartilage（軟骨）, not bone, their fossils are very fragile and are usually found in flattened parts, making it impossible to study the shape of these internal structures. But the Ozarcus mapesae specimen（標(biāo)本）was preserved in a nearly three-dimensional state, giving researchers a rare glimpse at the organization of the arches in a prehistoric animal.

"This beautiful fossil offers one of the first complete looks at all of the gill arches and associated structures in an early shark. There are other shark fossils like this in existence, but this is the oldest one in which you can see everything," said John Maisey, a curator in the Museum's Division of Paleontology and one of the authors on the study. "There's enough depth in this fossil to allow us to scan it and digitally dissect out the cartilage skeleton."

Working with scientists at the European Synchrotron, the ESRF, Pradel imaged the specimen with high-resolution x-rays to get a detailed view of each individual arch shape and organization. "We discovered that the arrangement of the arches is not like anything you'd see in a modern shark or shark-like fish," said Pradel. "Instead, the arrangement is fundamentally the same as bony fishes."

The authors say it's not unexpected that sharks -- which have existed for about 420 million years -- would undergo evolution of these structures. But the new work, especially when considered alongside other recent developments about early jawed vertebrates, has significant implications for the future of evolutionary studies of this group. "Bony fishes might have more to tell us about our first jawed ancestors than do living sharks," Maisey said.

【1】What does the underlined word “that” in Paragraph 1 refer to?

A. Living sharks are quite advanced in evolutionary terms.

B. Sharks have kept their basic “sharkiness” over millions of years.

C. The jaw structures of modern sharks are similar to those in fishes.

D. Shark’s jaws have remained almost the same over millions of years.

A. there are only a few shark fossils

B. shark skeletons are made of bones

C. their fossils are often in poor condition

D. their fossils are found in a nearly three-dimensional state

【3】According to Paragraph 4, the shark fossil used in the study is .

A. the only complete shark fossil

B. the oldest complete shark fossil

C. the only Ozarcus mapesae specimen

D. the biggest Ozarcus mapesae specimen
